Foodcare pH Electrode with Long, Thin Body for Dairy Products & Semi Mature Cheese

$399.00

The FC250B is a glass body, single junction pH electrode that has a BNC connector. The very small 4 mm diameter of the FC250B is protected by an ultra slim glass body that is 150 mm (5.9 ") long; an ideal diameter is for small containers and test tubes. The FC250B also features an open junction design with viscolene gel electrolyte, a sensing bulb made of general purpose glass, and a conical tip shape. This design consideration is ideal for pH measurements in cheese, dairy products, and quality control processes. The recommended operating temperature range is from 20 to 40°C.

Hanna Instruments offers a wide variety of pH electrodes that are designed for many different applications. The type of glass used for sensing pH, bulb shape, body material, type of junction, type of reference and electrolyte used are just some of the design considerations.

The FC250B uses General Purpose (GP) glass, conical bulb, AISI 316 stainless steel body, and open junction with viscolene gel electrolyte.

General Purpose Glass Formulation

General Purpose (GP) glass, as the name implies, is a standard glass formulation that is used for general use. A pH electrode with GP glass will have a resistance of 100 megaohms at 25°C and is suited for measuring pH of samples that are at ambient temperatures. The FC250B is suitable to use with samples that measure from 20 to 40°C.

Conical Glass Tip

The conical-shaped tip design allows for penetration into solids, semi-solids, and emulsions for the direct measurement of pH in food products.

Open Junction Reference

Suspended solids and proteins found in food products will clog a conventional ceramic reference junction. This clogging will impede the measurement circuit between the indicating electrode and the internal reference resulting in slower response time, erratic readings, and frequent electrode replacement. The open junction design consists of a solid gel interface (viscolene) between the sample and internal Ag/AgCl reference. This interface not only prevents silver from entering the sample, but also makes it impermeable to clogging, resulting in a fast response and stable readings.

BNC Connector

The FC250B uses a BNC connector. This type of connector is universal in that it can be used on any pH meter that has the female BNC probe input. Other type of connectors include DIN, screw type, T-type, and 3.5mm to name a few. These types of connectors tend to be proprietary for a particular type of meter and are not interchangeable.
